Katajanokan vanhin osa kaavoitettiin 1800-luvun lopulla ruutukaavaperiaatteella, mutta saaren muodosta johtuen katuverkostojen suuntien liitoskohtiin muodostui muutamia teräväkulmaisia tontteja.
Purjekadun rajaama, kahdesta tontista yhdistetty kokonaisuus muodosti oman korttelinsa.
Umpikorttelissa terävän kulman asunnot olisivat muodostuneet ongelmallisiksi, joten korttelin pihat avattiin molemmille kaduille.
Kortteli raunioitui kärkeä lukuun ottamatta jatkosodan pommituksissa 1944.
